SPECIFICATION forming part of Letters Patent No. 422,011, dated February 25, 1890.

Application filed December 6, 1889. Serial No. 332,789. (No model.)

T VZZUwv/om it may concern:

Be it known that I, VILLIAM II. DANIELS, a

` citizen of the United States, residing at St.

Louis, in the State of Missouri, have invented a certain new and useful Car-Axle Lubricator, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification. Y

My invention relates to that class of caraxle lubricators in which a roller is interposed between the oil carried in the lower part of the box and the journal, in order to convey the oil to the journal as it and the roller rotate. The level of the oil in the box must, of necessity, be below the level of the opening between the lower part of the axle and the box; otherwise the oil would 4flow through said opening.l The journal itself, therefore, cannot be made to run in oil, and some means must be interposed between the oil in the lower part of the box and the journal to convey the oil to the journal.

The invention consists in a roller swung from a shaft journaled by the box itself, the lower part of which roller dips in oil or other lubricant in the bottom of the box and conveys the oil to the lower part of the journal by being frictionally rotated by said journal as it revolves.

The invention also consists in a novel means for holding said shaft in its keyed-up position, and in means for permitting play of the drip-collar, and in certain other details of arrangement and construction, which will be set forth in full, and particularly pointed out in the claims making a part hereof.

Figure 1 is a sectional elevation, in the direction of the axle and journal, of a car-axle lubricator made in accordance with my invention, the same being taken on the line 1 1 of Fig. 2. Fig. 2 is a vertical cross-sectionof the same on the line 2 2 of Fig. 1. Fig. 3 is a horizontal cross-section on the line 3 3 of Fig. 2; Fig. 4, a vert-ical section on the line il 4C of Fig. 1, and Figs. 5, 6, and 7 views of details.

10 is the caraxle, 11 the journal thereof, and 12 the ordinary box that surrounds the journal and supports the body of the car.

13 is the usual brass or anti-friction metal ber to prevent the dust from enteringv thebox and commingling with the lubricant.

Theentrance to the box is by the usual lid 16, which is hinged to the box and has anose 17, that is adapted to catch over the free en ds of a spring 1S, which is secured to the under side of the box.

The foregoing features form no especial part of my invention.

In the lower part of the box, to one side thereof, I arrange a shaft 19, which is journaled at one end in the box and is journaled at the other end by a notched lug 20, that is secured to the side and bottom of the box and may form a part thereof. The lower part of the notch forms a bearing for the journal, and the notch is so shaped that the end of the shaft may be easily inserted and withdrawn from the notch by lifting up th-e end of the shaft. Said lug has a nose 21, that overhangs the notch and prevents the shaft 19 from being vertically displaced from its bearing therein. To" said shaft, at or about the middle thereof, I rigidly attach a hanger 22, which carries a roller 23, the upper part of which is adapted to bear against the lower side of the journal 11, and the lower side of which runs in oil or other suitable lubricant carried in the lower part of the box. This roller and hanger are preferably held up to the journal 11 by means of a bent fiat spring 24, of the form shown in Fig. 6, the bend of which takes around a pin 25, projecting from the shaft 19. rIhe free ends of the spring 24 bear against a part of the hanger 22, and thus the roller is kept up to its work.

To the shaft 19, near the dustguards, is rigidly secured a second hanger 26, which supports a drip-collar 27, that is placed about half around the lower part of the journal, near the axle, and abuts against the shoulder of the axle. The dripcollar 27 is carried by a small upright 2S, which is loosely mounted on the shaft 29 of thehanger 26 and plays between the two ends of said hanger. Encircling the shaft 29 is a spiral spring 30, which bears against the upright 28 and holds ICO the drip-collar 27 against the shoulder of the axle, but allows it to play back and forth as the axle works back and forth in its bearing, which it is liable to do, especially when the wear of the brass 13 is considerable. This second hanger 26 holds the drip-collar up to A the journal by means of a bent flat spring 31,

secured to the shaft 19 in the manner previously described with reference to the bent spring 24. I bevel the upper ends of the dripcollar 27 at 32 in order to have the surplus oil that is on the journal 11 as it rotates delivered back to the box, instead of passing -out around the axle 10 as it ordinarily would. The thin beveled end of the drip-collar skims the surplus oil off of the journal near the axle and causes this surplus oil to flow down the incline of the bevel back into the box, instead of passing out between the axle and box.

To prevent the oil or lubricant in the lower part of the box from passing out between the lower partof the box and the lower part of the axle 10 as the oil surges back and forth, I provide the drip-collar 27 with wings 33, which the oil will strike against as it swash'es the lower part of the axle and the box. In practice the hanger 26 may be made to serve the purpose of one of the wings33, and prevent the oil as it surges back and forth in the lower part of thc axle-box from passing out through the opening between the lower part of the axle and the box.

The end of the shaft 19, near the lug 2`O,is

made angular and preferably octagonal in shape, and is provided with a curved arm 34, which is made to correspond with the octagonal end of said shaft 19. The end of the curved arm 34k engages an angle-iron 35, secured to the box near the lid 16. A certain amount of play is allowed between the arm 34 and the shaft 19 in the direction of the arm and length of said shaft, so that said arm can be moved from the-path of the angleiron 35. The lid 16 carries a lug 36, which, wheny the lid is down in place, closes the open side of the angle-iron 35, and thus securely locks iniposition the arm 341-. The object of the arm 34; is to hold the shaft 19 when keyed up, so as to make the roller 23 and the dripcollar 27 bear against the axle and maintain said parts in contact with the axle at any required pressure, so that when the brass 13 .wears away the roller and drip-collar can still be kept up to their work against the journal. The shaft 19 may be keyed up by a wrench, and when the roller and drip-collar bear against the axle with the required force the shaft is held in position and the arm 34 slipped over the angular part of the shaft and made to engage the angle-iron 35.

In order to be able to place a new brass in the' box without unshipping the parts of the lubricator, I provide the box with a dcpresn sion 37 beneath the roller 23, so that said roller and drip-collar may be sufliciently depressed in order to allow the old brass to be taken out and a new one inserted without removing the lubricator.

My lubricator can be applied to any ordinary car-axle box by providing a journalbearing for the shaft 19 at one end of the box, and furnishing said box with a notched lug 2O and an angle-iron 35, and securing to the lid 16 a lug or other means to lock the arm 34' in place. By raising the lid 16 the arm 34 may be disengaged from the angle-iron 35, the play of the arm, before referred to, allowing it to be moved out of the path of the angleiron, and the shaft 19, carrying the roller 23 and drip-collar, may then be removed from the box. The parts are very compactly-arranged and the construction very simple. All

\ the parts of the lubricator may be removed from and replaced in the box without in any way disturbing the journal and brass.

Various changes may be made in the construction of the apparatus without departing from the spirit of my invention, and I do not wish to limit myself expressly to the exact de'- vices herein described. back and forth in the box, and thereby pre- 1" vent the lubricant from passing out between Vhat I desire to claim isl. A car-axle lubricatorconsistingof ashaft journaled by the box thereof, a roller swung about said shaft, the lower part of which runs in oil and the upper part of which bears upon the lower part of the journal and distributes oil to the same,- and an arm engaging with an angular portion of said shaft for keying up the same and keeping the roller to its work. 2.
